HISTOMORPHOLOGICAL POSTNATAL DEVELOPMENTAL STUDY OF THE OVARIES OF THE LOCAL RABBITS (Oryctologus Cuniculus)

Abstract

This investigation was carried out to point out structural histomorphological changesthat take place in the ovaries of female local rabbits at three different postnatal periodsof their life that were kitten, immature and mature does. To conduct such project, 24rabbits were collected (8 for each age) from the local breeders. Rabbits were euthanized,dissected and subsequently ovaries were collected and fixed with 10% neutral bufferedformalin then subjected to routine processing such as dehydration, clearing, embeddingand block preparation. Finally, sections of 6 µm were prepared and stained withhematoxylin-eosin and Masson’s trichrome stains. Gross findings showed twofunctional bilateral elongated triangular-shaped ovaries situated in the abdominal cavitysuspended by mesovarian ligament with absence of true ovarian bursa. Microscopicfindings revealed prominent structural changes in the ovaries of immature doescompared to those of kittens and mature does indicated that immature does after theperiod of weaning face great developmental growth and changes
